Application filed August 28, ,1909. Serial No. 515,028.

i To all whom it my concern:

I Be it known that I, Ar nnn'r BUoKiUs, T13, of Chicago, Cook county,'Illin'ois,have

invented anew and useful Improvement in Truck Side Frames, of whichtl-iefollowmg is a full, clear, and exact description, refe ence beingbad to the accompanyingjdi'lti ings, forming part"'of thisspecificati'onjfin which Figure l'is a front elevation 0f'lily'llnproved side frame; Fig. 2 is a top plan view partly in section; Fig. 3is aside elevation of the journal boxwhich I prefer to use;

Fig. 4 is an enlarged detail view showing the preferred form ofconnection; Fig. 5.is

a-view similar to Fi 1 showin a modified form of connection betweenthetruck frame and the journal box, and Figs. 6 and 7 are enlargedviews'similar to Fig. 2 showing modified forms of connecting the truckframe and journal box.

My'inv'ention relates to truck side frames and particularly to theconnection of the journal boxes therewith.

1 The object of the invention is to provide a cheap, simple and improvedconstruction by whichthe journal boxes may besecured to the side frame."a

In the drawing, 2 represents a cast truck frame, shown as in one piece,though any desirable number of parts may be used. This frame may be ofany desirable shape and size, as this is not a part of my invention. Theend portion of the frame is provided with a partial yoke or str: 3forming a top and side portion, each 0? which is provided withprojecting edgclips .or ribs. The vertical ribs are shown at 4, in Fi2,.while the horizontal ribs are indicated in Figs. 1 and 2. The yokewalls having these ribs may be either straight sided or tapered fromoneend toward the other.

The journal box 5, shown in Fig. 3, 15 provided with straight or conver'ng'undereut metal shrinks in cooling, it will draw toward this corner.This corner corresponds to the inner corner of the yoke opening, and asthe metal shrinks, it Wlll draw tightly into the converging recesses ofthe ribs.

In the construction shown in. Figs. 1 to 4, I place the journal boxes ina suitable mold, and pourmolten metal therein to form fend-when. themetal cools the shrinkage of draw the boxes against the the straps willside frame, and rigidly secure it thereto.

In the construction shown in Fig. 5, the

journal box is provided with the converging undercut ribs 7* and 7 onthe top and bottom thereof, respectively, and with straight undercutl'llJS 6 on one side, which forms a continuation of the ribs 'Zfand 7.-The frame 2 is cast with a strap or yoke composed of' the members 3, land 3, which engage the l'lbS on box. Tins order of casting may bereversed by first casting the side frame and placing it in a suitablemold, and then pouring the molten metal therein to .form the journalboxes. The ribs- 6 6*, and 7, 7, are parallel toeach other, and are castaround the straps 3 when the metal is poured into the mold to form thebox, as shown in Fig. 6.

In Fig. 7 I have shown still another inodi-' fication in which the frameand journal boxes are formed separately, the frame having a. strap 3 ofless width than the strap shown in Figs. 1, 2 and 3. This strap is alsoprovided with ribs 4*. The box is provided with converging under outribs 6 and 7 similar to the box shown in Figs. 1 to at.

The boxes are assembled with the frame, given their proper spacing apartand alinement and moldin material is then placed outside the ribs 0 thebox on both top and inner side. Metal is then cast into the spacesbetween the box ribs and the frame llps, as shown at 8, 8. This metalsecures the box firmly in )lace and extends over the 1 top and inner sie, and drawing into the undercut ribs more firmly as it shrinks incooling. I

The advantages of myinyention will be apparent to those skilled in theart. A boltless side frame may thus be obtained in a simple manner andat small expense. The journal boxes are firmly held in place by thelocking metal, and different metals may be employed for the journalboxes and the frame.

' Man-y variations may be made in the form substantially as described.

4. truck side frame having separately formet j'ournalboxes, recesses insaid boxes, and ribs formed integrally with the frame cast in therecesses to form a cast joint; sub stantially as described.

(5. A truck side frame having separately formed journal boxes, recessesin said boxes, ribs on said frame for engaging the recesses in the box,the. frame and journal boxes being united by means of a cast joint;substantially as descrlbed.

7. The method of making truck sideframes having separately formedjournal boxes, which consists in rst casting oneof said members, thenplacing said member in a mold, and then casting the other member in saidmold to form a cast joint between.

9. The method .of making truck side frames having separately formedjournal boxes, which consists in first forming the ournal boxes withconverging recesses, then placing said boxes in a mold, and then cast,-
